To commemorate the 70th anniversary of Suzhou's liberation, the Suzhou Boyang Chemical Party Branch organized all party members (including activists) to watch the patriotic film "Founding the Great State" during the noon lunch break on April 19, 2019, which tells a series of stories from the end of the Anti-Japanese War to the eve of the founding of the People's Republic of China in 1949, with the main line being the preparation of the first plenary session of the Chinese People's Political Consultative Conference, highlighting the formation of the multi-party cooperation and political consultation system led by the Chinese Communist Party at that time.
